New eye scan could spot drug damage before vision fades

NCT ID NCT07409740

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study will use a non-invasive eye scan called OCTA to look for tiny blood vessel changes in the retina of 90 adults who have taken hydroxychloroquine for at least a year. Hydroxychloroquine, used for autoimmune diseases, can sometimes harm the retina with long-term use. The goal is to see if OCTA can detect early signs of damage, which could help doctors monitor patients more closely and prevent vision loss.
